If the inductance " ESL " is small, the dissipation factor can be approximated as:
12.
The " phase " of the impedance is specified as dissipation factor \ tan \ delta.
13.
It consists of a " puck " of ceramic that has a large dielectric constant and a low dissipation factor.
14.
The losses of film capacitors and some class 2 ceramic capacitors are mostly specified with the dissipation factor tan ?.
15.
If the capacitor's inductance " ESL " is small, the dissipation factor can be approximated as:
16.
Class 1 capacitors with very low losses are specified with a dissipation factor and often with a quality factor ( Q ).
17.
The large range of values for the dissipation factor includes both typical and maximum specifications from data sheets of the various manufacturers.
18.
Also, the temperature and frequency dependence of the dissipation factor are higher for polyester film capacitors compared with the other film capacitor types.
19.
The temperature and frequency dependence of the electrical characteristics for capacitance and dissipation factor of PEN film capacitors are similar to the PET film capacitors.
20.
The permissible changes of capacitance, dissipation factor and insulation resistance vary with the film material, and are specified in the relevant data sheet.
